1. Prepare a thick piece of art paper and draw a cross in its center. Point a point at two positions equidistant from the top edge of the paper, and then gently connect the two points with a pencil to draw a horizontal line.
Put a point above and below the midpoint of the horizontal line, and then gently connect them with a pencil to draw a vertical line. The final effect is as shown in the figure:
2. Draw a big circle with compasses. In this example, we assume that the circle is 9 cm straight. This circle will be the outermost boundary of the compass.
3. Mark a point with a pencil at 45, 135, 225 and 3 15 with a protractor, and then connect the points at 45,225 and 3 15 and 135.
4. Mark the following positions with a protractor: 22.5.
67.5
1 12.5
157.5
202.5
247.5
292.5
337.5
5. Connect the points in the following order: 22.5 and 202.5.
67.5 and 247.5
1 12.5 and 292.5.
157.5 and 337.5
6. Draw a concentric circle with a radius of 6 cm.
7. Draw another concentric circle with a radius of 3 cm.
8. Draw an arrow in the basic direction. Connect the position of 0 (n) on the outermost ring with the position of 45 on the innermost ring. Similarly, connect the position of 0 (n) on the outermost ring with the position of 3 15 on the innermost ring.
Repeat the whole process. Compare the outermost 90 (e) position with the innermost 45? And135; Connect the position of 180 (s) on the outermost ring with the positions of 135 and 225 on the innermost ring; Connect the position of the outermost ring 270 (w) with the positions of the innermost rings 225 and 3 15. Finally, your compass looks like this:
9. Draw an arrow in the secondary direction. Connect the intersection of position 45 (NE) and the true north arrow on the outer ring with 22.5 lines. Similarly, use line 67.5 to connect the intersection of position 45 (NE) on the outer ring and the true north arrow.
Repeat this process. Connect the position of 135 (SE) on the outer ring with the intersection point of the east arrow and the intersection point of the right side of the south arrow respectively; Connect the 225 (SW) position on the outer ring with the intersection of the left side of the due south arrow and the intersection of the upper and lower points of the due west arrow respectively; Connect the position of 3 15 (NW) on the outer ring with the intersection of the upper part of the due west arrow and the intersection of the left part of the due north arrow. Finally, your compass looks like this:
10, draw the outermost arrow. Connect the 22.5 (NNE) position on the outer ring and the intersection of the middle ring and the right side of the true north arrow. Then connect the 22.5 (NNE) position on the outer ring and the intersection of the central ring and the northeast arrow. Repeat this process. Connect the position of 67.5 (ENE) on the outer ring with the intersection of the central ring below the northwest arrow and the intersection of the central ring above the due east direction.
Connect the position of 1 12.5 (ese) on the outer ring with the intersection below the east arrow of the central ring and the intersection above the southeast of the central ring respectively.
Connect the position of 157.5 (SSE) on the outer ring with the intersection below the arrow in the southeast direction and the intersection between the central ring and the right side in the south direction.
Connect the position of 202.5 (SSW) on the outer ring with the intersection of the south central ring and the left side of the arrow, and the intersection of the central ring and the lower southwest direction respectively.
Connect the position of 247.5 (WSW) on the outer ring with the intersection point of the middle ring below the southwest arrow and the intersection point of the middle ring below the south direction.
Connect the position of 292.5 (WNW) on the outer ring with the central intersection point above the arrow in the due west direction and the central intersection point below the northwest direction respectively.
Connect the 337.5 (NNW) position on the outer ring with the intersection of the central ring and the northwest arrow, and the intersection of the central ring and the left side of true north. Finally, your compass looks like this:
1 1, as shown in the figure, indicate the name of each arrow:
